Subject: [PATCH 5/5] daemon: fix wayland detection when deciding to bypass
Xsession
At the moment if there's a session file with the same name in
both /usr/share/xsessions and /usr/share/wayland-sessions, GDM
will think the wayland is getting used when deciding whether or
not to bypass the /etc/gdm/Xsession script, even if wayland is
explicitly being ignored.
This commit fixes the check.
